OILING SYSTEM FOR GASOLINE ENGINES.

Application filed May 3, 1921. Serial No. 466,555.

T all whom it may concern.

Be it known that I, RALPH ANnnRsoN, a citizen of the United States, and resident of Fresno, in the county of Fresno and the State of California, have invented a new and useful Improvement in Oiling Systems for Gasoline Engines, of which the followis aspecification.

Iy invention relates to an oiling system for a gasoline engine, and more especially to an engine having the fly wheel encased in a housing and submerged in oil. It is especially adapted to be attached to an engine of the type used on a Ford automobile. The objects I have accomplished in the oiling of the connectingrod bearings by means of a spray of oil directed against the bearings which is forced into circulation by the revolution of the fly wheel. By this means the bearings are kept thoroughly oiled when the engine is in operation, and the faster the engine runs the greater the spray of oil directed on the bearings. Another object accomplished is that the distribution of the oil is not affected whether the engine is standing on a level or on an incline. Another object is the simplicity of the de vice and the fact that it can easily be installed on engines of the type described and can be used as an auxiliary system to other systems of oiling. I accomplish these objects by means of the device described in the specifications hereinafter set forth and illustrated on the accompanying drawing in which Figure 1 is a side view of an engine and the housing, partly in section, showing the device installed thereon. Figure 2 is a receiver or cup adapted to catch the oil from the flywheel. Figure 3 is any inside view of the plate or cover for the lower part of the crank case. Figure I is an outside view of the plate shown in Figure 3 showing a portion of the oiler attached thereto.

In said drawing Bis the housing of the portion of the engine and the lower part of the crank case. C is the lower cover of the crank case. D and D are connecting arm bearings fitted on the cranks F and F 1 which cranks form a part of crank shaft E. G is the fly wheel which rotates with the crank shaft. 0 is the oil reservoir in the engine housing and O is the oil level in the reservoir. The auxiliary oiling device which I have invented is described as follows: 2, 2 and 2 are depressions in the crank case cover which are directly under the connecting rods. These depressions are. in the present construction, adapted to hold oil so that when the connecting rod is at the lower end of its downward movement it dips slightly in the oil. To the under side of the plate 0, I have attached a pipe 3 so that it extends across the under side of said depressions 2, 2 and 2 and I have made an opening through the plate (3 within the depressions and through the pipe 3. These openings on the drawing are indicated as 3, 3 and 3. 3 is a plug in one end of pipe 3. 5 is a receiver or cup adapted to catch the oil. It consists of a receptacle attached to the inside of the housing of the engine, directly under the fly wheel and submerged in oil, the mouth of the receptacle being on the side and turned so that when the wheel is normally rotating centrifugal force will throw the oil into the cup. Receiver 5 has an opening through the bottom and a lead 6 which connects the opening in cup 5 with the pipe 3. 6 and 6 are connections for attaching lead 6 to pipe 3 and to cup 5. For the purpose of adapting the cup 5 to be attached to a Ford automobile engine housing I have placed a screw thread 5 on the cup which is the samethread in the drain hold in the bottom of engine housing.

It will be noted that as the receiver is submerged in the oil and the fly wheel is rotating in a common plane with the cup and is also submerged in oil, that a current of oil will be constantly moving toward the mouth of the cup while the fly wheel is rotating and the pressure thus produced in the cup will force the oil through the lead 6 into pipe 3 and through the spray openings 3, 3 and 3, thus directing a constant spray of oil against the connecting bearings when the engine is in motion. After the oil has been sprayed it can flow along the bottom of the housing and return to the oil reservoir O. r

I claim as new and ask for Letters Patent: 1. In combination with an engine having the bearings and the fly wheel enclosed in fly Wheel, and in the oil reservoir With the open end of the cup toward the direction the fly Wheel is rotating, and a lead from said cup to portions of the housing adjacent to bearings of said engine.

2. In combination With an engine having the connecting rods and the fiy Wheel enclosed in a housing, said housing in part forming an oil reservoir in which the fly Wheel is partially submerged, of a cup within the reservoir and adjacent to the under portion of the fly Wheel, said cup being positioned so that the mouth of-the cup is open toward the flow of the oil created by the revolution of the fly Wheel, and a lead from the cup to a plurality of spray openings through the housings, substantially as described.

33. In combination With an engine having the connecting rods and the fly whee]. en-

closed in a housing, said housing in, part forming an oil reservoir in Which the 'i'iy Wheel is partially submerged, of a cup Within the reservoir and adjacent to the under portion of the fiy Wheel, said cup being positioned so that'the mouth of the cup is open toward the flow of the oil created by the revolution of thefiy Wheel, and a lead from the cup to openings through the hous ing said openings being adapted to throw a spray of oil, substantially as describ d.
